What Dust May Have To Do With Earth’s Rapidly Warming Poles
As earth’s climate warms, scientists have tried to understand why the poles are heating up two to three times faster than the rest of the planet. Airborne dust, it turns out, may play a key role.

Role-Reversal (and Some Fun) at AGU
Francesco Fiondella is normally behind the scenes writing web stories, developing audio slideshows and videos for the International Research Institute for Climate and Society (IRI). But at this year’s annual American Geophysical Union (AGU), the tables were turned for a brief moment. He was video ambushed by climate scientist Andrew Robertson and forced to explain…

Clues from Last Ice Age May Hint at Drying Ahead for Some Regions
In the spectacular collapse of ice sheets as the last ice age ended about 18,000 years ago scientists hope to find clues for what regions may grow drier from human caused global warming. In a talk Thursday at the American Geophysical Union’s annual meeting, Aaron Putnam, a postdoctoral scholar at Lamont-Doherty Earth Observatory, painted a…

Improving the Water Outlook in the Himalayas
Andrew Robertson, a climate scientist at the International Research Institute for Climate and Society, discusses his research on helping reservoir managers in northern India make better planning decisions by improving their ability to predict how climate change will influence water availability.
AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
